Guidance and Manufacturer's Declaration - Electromagnetic Emission
The Model TX-22 White is intended for use in the electromagnetic environment specied below.
The user of TX-22 White should assure that it is used in such an environment.
Emission test Compliance Electromagnetic Environment - Guidance
RF emissions CISPR 11 Group 1
The Model TX-22 White uses RF energy only for its internal function.
Therefore, its RF emissions are very low and are not likely to cause any
interference in nearby electronic equipment
RF emissions CISPR 11 Class B
TX-22 White is suitable for use in all establishments, including domestic
establishments and those directly connected to the public low-voltage power
supply network that supplies buildings used for domestic purposes
